The proposed development is situated between the Swartkops and Coega River valleys some 20 km to the north of the city centre of Port Elizabeth. The project involves the development of land, services and top structures to accommodate people in need of housing. The project proponent is the Nelson Mandela Bay Municipality (NMBM), who has appointed GOBA Consulting Engineers & Project Managers (GOBA (Pty) Ltd) to act as project managers to help alleviate the housing backlog in the municipality. 1.1 Motivation for the proposed activity 1.1.1 Recipients of government subsidised social housing The Motherwell housing project aims to provide serviced low cost housing for low or no income families that qualifies for government housing subsidy and have been identified by ward councillors across the metro as recipients of low income housing. These identified recipients are, amongst others, victims of the 2006 floods in the Swartkops flood plain, occupants of informal settlements in retention ponds, within the servitude areas of power lines, living within the road reserves of roads earmarked for upgrade, and recipients living in and around the New Brighton dump site. These families constantly experience adverse weather conditions, especially during the cold winter months and rainy autumn and spring periods, and are constantly subjected to health threatening conditions. During heavy rains shacks are often flooded or destroyed, and strong winds frequently cause fires to spread rapidly in informal settlements. 1.1.2 Health and environmental concerns Many informal settlements located within the Swartkops River flood plain are not serviced and the residents mostly use the bucket system to dispose of their sewage. As a result residents often empty their buckets into the stormwater drains, drainage channels or vegetated areas. This practice, for example, was recently noted in the KwaZakhele area next to the Swartkops estuary. This poses a major health and environmental threat to the people residing in the flood plain and the Swartkops River and estuarine ecosystems. Raw sewage entering the Swartkops estuary causes the introduction of high nutrient levels into the estuary, which may lead to eutrophication of the estuary. Eutrophication is one of the principal threats to coastal ecosystems, especially urban estuaries, and may cause changes in the community structure and biodiversity patterns of the Swartkops estuary.
